Delete emails will delete VM (Voicemail) on Unity Connection 8.0

Dear NetPro gurus,

One of my customers have recently bought a new Cisco Unity Connection 8.0. They are currently using Microsoft Outlook (with Microsoft Exchange) and they are currently setup with SMTP Smart Host so whenever they got a new Voicemail on their Cisco IP phone, they will automatically receive a new email with WAV attachment on their Microsoft Outlook.

However, what they found is say when they have 20 x new Voicemail messages, they will have 20 x emails with WAV attachments which is normal. But when they listen and delete all their email attachments, they still have to go to their Voicemail inbox on their IP Phones by pressing the 'Envelope' button and delete the SAME 20 x Voicemail messages before their MWI will go off.

What my customer wants is there any method when my customer delete all their emails on Outlook, the voicemail on Unity Connection will too be deleted at the SAME TIME, and also the MWI will turn off the SAME TIME??
